I would also like to see the results of scientifically run double blind testing with enough trials that demonstrate statistical repeatibility in which the golden-eared crowd are involved and not people like me that cannot clearly hear the differences.

from link in post #5...

Having said all this, are there really any significant audible differences between most cables that can be consistently identified by experienced listeners? The answer is simple: very seldom! Those who claim otherwise do not fully grasp the power of the old Placebo-Effect - which is very alive and well among even the most well-intentioned listeners. The placebo-effect renders audible signatures easy to detect and describe - if the listener knows which cable is being heard. But, take away this knowledge during blind or double-blind listening comparisons and the differences either disappear completely or hover close to the level of random guessing. Speaking as a competent professional engineer, designer and manufacturer, nothing would please me and my company's staff more than being able to design a cable which consistently yielded a positive score during blind listening comparisons against other cables. But it only rarely happens - if we wish to be honest!

Oh yes, we have heard of golden-eared audiophiles who claim to be able to consistently identify huge, audible differences between cables. But when these experts have visited our facility and were put to the test under carefully-controlled conditions, they invariably failed to yield a score any better than chance. For example, when led to believe that three popular cables were being compared, varying in size from a high-quality 12 AWG ZIP-CORD to a high-tech looking cable with a diameter exceeding an inch, the largest and sexiest looking cable always scored best - even though the CABLES WERE NEVER CHANGED and they listened to the ZIP Cord the entire time.

Sorry, but I do not buy the claims of those who say they can always audibly identify differences between cables, even when the comparisons are properly controlled to ensure that the identity of the cable being heard is not known by the listener. We have accomplished too many true blind comparisons with listeners possessing the right credentials, including impeccable hearing attributes, to know that real, audible differences seldom exist - if the comparisons are properly implemented to eliminate other causes such as system interactions with cables, etc.

Indeed, during these comparisons (without changing cables), some listeners were able to describe in great detail the big differences they thought they heard in bass, high-end detail, etc. (Of course, the participants were never told the NAUGHTY TRUTH, lest they become an enemy for life!)

I won't get into this.

Perhaps because you can't quote a blind test of any sort to substantiate it? Not trying to be offensive, but I have looked long and hard for any blind testing that proved any significant differences, and many that proved otherwise. Changes to capacitance of the cable, circuits added fore or aft, can make subtle changes, but even those are far from substantial.

If you have such evidence, please show them! :thmbsp:

Somehow, I wouldn't put a lot of money on that right now.

There are three topics about you can't have a rational discussion: religion, politics and now... speaker wire!.
But the first two are far from being a science. The third can and must be discussed, in a civilized way, with numbers and replicable experiments and not "personal impressions" , or dismissing out of hand other people who "can't hear" whatever that means. This is not an act of faith. This is physics!.
And thinking about it...this is funny because usually the true believers are those who adamantly refuse to engage in an intelligent discussion when somebody challenge their faith, about politics, religion...or speaker wire.:music:

I really do not see why I would need to. I have heard the difference, people I know have heard the difference and people I know that have listened to my systems and others during cables swaps who know nothing about audio or cables at all; have heard the difference.
Why would I really be concerned about some test someone wants to run in a lab somewhere, when it has already been proven to me and many others?

Every cable has a different construction, metal, purity of the metal, insulator, connector and winding. While two cables of the same gauge might be able to transfer the same amount of energy, how does this account for the discrepancies in their construction? How does ohm's law apply to the effects of EMI or astronomical anomalies on the cable? How do we measure how well a connector makes contact with thousands of different amplifiers and speaker terminals? How do we determine what is the best cable insulation and capacitance to work on all systems, in all homes with various different types of interference like EMI?
Why do you dismiss discrepancies that may exist even though they can't be proven by scientific tests and our limited knowledge of the universe in 2007?
The best judge is the human experience, which is something that neither science nor any lab test may ever be able to approach. Aside from determining proper gauge to handle the power, resistance and some other measurable specifics that are required, I think our knowledge of physics needs to be taken with a great deal of salt. Look at how many "facts" have been blown apart in just the last 100 years.

As far as the blind testing is concerned, I did my own with others and witnessed the results. I know what they are. If someone wants to attempt to conduct a non biased one here, I think that would be great.

Some people hear more than others, especially people that have trained themselves to be critical listeners and have a great deal of experience with a broad array of different equipment. There are many people that cannot, or rather, do not want to hear a difference. Those of you here with significant others know exactly what I am talking about.
However, even the best of critical listeners sometimes can only hear within the range of their biology. Outside of the realm of hearing loss, due to the size and shape of their ears, people either hear: similarly, more or less. No one is the same.
"Psychoacoustics" also plays a huge role. There is no question at all that there are people that claim to hear things that may or may not be present. Placebo does play a role when we deal at such an extreme. It should also be noted that it works the other way as well. There are people that do NOT want to hear a difference, and regardless of whether there may or may not be a difference in sound, their subconscious will not allow them to hear it. Economics plays a HUGE role in this. If someone can't afford something, but needs to retain a high level of pride in themselves, they will look for every conceivable reason to justify why they did not or could not spend more money on a different product. This is exists with audio, cars, houses... everything. It is as much of human nature as sexual desire and it is something that people cannot control.

When I look at cable, I look at price last. Not everyone can do this. I listened to a variety of different cables and choose the ones that I think sound the best with my equipment in ways that I can clearly hear. More often than not, it isn't the most expensive or fanciest looking cable that wins the audition.

I have no intention of coming on here and trying to convince someone who already has their mind made up to change the way they think, because I know I can't. I certainly don't plan on getting my point across by making rude comments like some others have. I am merely offering my opinion on the matter and defending my comments. If you agree with me, than we have something in common. If it made you think twice about your opinions on the matter, than that was the intended effect. If you simply want to dismiss my comments, it would be impossible for me to care any less.

One thing we should not forget, is while our opinions and perceptions may vary for what ever reasons we have or external forces that exist, we are still all lovers of this hobby.
 
the funny thing is no one bothers to "tune" the room first before embarking on the long and lonely trail of updating their systems it is always a after thought :scratch2:

Not me, my desire for a Ferrari is oh so strong and I can't come up with one reason or justification of why I couldn;t or shouldn't, except for one, I can't afford it. But it is one hell of a desirable performance car.;) Now when it comes to speaker cables over $10k, I can easily talk myself out of it although I have heard them and there is an improvement and I can afford them. Simply not worth it to me but I respect the opinions and actions of others who do justify that kind of expense on their system.
 
Time to move this to Thinking Out Loud forum which is what I should have done first thing this morning. :)

That would be refreshing
with numbers and replicable experiments

In other words, the "civilized discussion" must take place only within the rigidly defined framework of your position on the subject.

and not "personal impressions" , or dismissing out of hand other people who "can't hear" whatever that means.

But dismissing out of hand people who "can hear" appears to be perfectly acceptable to you.

This is not an act of faith. This is physics!.

NO, actually this is a silly waste of time.
 
Well, I guess this one is heading in the same direction as all the others. How long do you figure we should let it sit before we hit that little silver handle on the top corner of the tank?

Your call Erik. Threads like this one will not die on their own I have found. :yes:

I bought my first set of really decent cables today(or at least in my limited experience).Audioquest type 4 w/banana plugs.The amp and the speakers are both new to my system,so it will be a while before I can really decide if theres a difference or not.But its nice to have something solid and stable to go with my electronics.
